NSTALLATION
Upon receiving the VWR Hotplate/Stirrer/Hotplate-Stirrer, check to ensure that
no damage has occurred in shipment. It is important that any damage that
occurred in transport is detected at the time of unpacking. If you do find such
damage the carrier must be notified immediately.
After unpacking, place the Hotplate/Stirrer/Hotplate-Stirrer on a level bench or
table, away from explosive vapors. Ensure that the surface on which the unit is
placed will withstand typical heat produced by the unit and place the unit a min-
imum of 15,2 centimeters from vertical surfaces. Always place the unit on a stur-
dy work surface.
The Hotplate/Stirrer/Hotplate-Stirrer is supplied with a power cord that is insert-
ed into the IEC connector on the back of the unit first, then it can be plugged
into a properly grounded outlet. The unit plugs into a 230 volt, 50/60 Hz source.
M & S
AINTENANCE ERVICING
T
he Hotplate/Stirrer/Hotplate-Stirrer is built for long, trouble-free, dependable
service. It needs no user maintenance beyond keeping the surfaces clean. The
unit should be given the care normally required for any electrical appliance. Avoid
wetting or unnecessary exposure to fumes. Spills should be removed promptly
after the unit has cooled down. Do not use a cleaning agent or solvent on the
front panel or top plate which is abrasive or harmful to plastics, nor one which
is flammable. Always ensure the power is disconnected from the unit prior to any
cleaning. If the unit ever requires service, contact your VWR representative.
CLEANING CERAMIC TOPS:
First remove any burnt-on deposits or spills from the top plate with a scraper
(similar to scraping paint off of windowpanes in your home). For your safety,
please wear an insulated mit when using a metal scraper. When the top plate has
cooled, apply a few dabs of a non-abrasive cleaner over the surface with a damp
paper towel. As a final step, clean with water and wipe surface with a clean, dry
paper towel.
CLEANING ALUMINIUM TOPS:
For simple dust and dirt, clean the aluminium top by using a damp cloth with
soap and water. For more stubborn deposits, try using a flat edge wooden spat-
ula to scrape off as much as possible. For more stubborn stains, try using a cou-
ple of tablespoons of white vinegar to two pints of water and mix well. Dip a
clean cloth into the mixture and gently rub the exterior of the aluminium sur-
face. Generally, it is not a good idea to use abrasive pads or cleaners on aluminium,
as the metal will scratch easily. If you must use some type of abrasive, try apply-
ing baking soda to the surface and then rubbing with a moist cloth. This will
work as well as most scouring pads and is less likely to create deep scratches in
the surface. Be careful not to use steel wool or scouring pads as they can leave
the aluminium riddled with little scratches that make it harder to clean in the
future. If you feel you must use steel wool, use the finest grade you can find
and use as sparingly as possible with as little pressure as possible. Go with the
grain rather than using circular motions.
